Flash Video Downloader is an application which allows you to easily batch download and save streaming flash videos from just about any website with streaming flash videos as long as the videos are set to autoplay (that is, they start playing when the page loads). Examples of sites are youtube.com, video.google.com, and dailymotion.com, but just about any website will work. Instead of sifting through the html code of the webpage to find the flash video, Flash Video Downloader 2 actually checks where the video is coming from and download it, which will ensure that it will still work even if the page has changed. It can even download videos that require you to login to the website and videos from websites that first play an advertisement. Flash Video Downloader 2 can also download up to 5 videos at a time in order to significantly improve the overall download time.

Version 2.0.1 is able to download from Dailymotion. I have tried twice and I got both FLV files.
I'm not sure yet if it works will all Dailymotion videos, but it's better now.
Thank you, dear developer, for the fast solution for this problem.

I've tried Flash Video Downloader 2 with YouTube, Veoh and Dailymotion URLs.
It works very well with YouTube and Veoh. It did not miss one single FLV file.
With Dailymotion it was able to download one single FLV file in six or seven tries. The other times it has downloaded pictures, banners or... nothing at all. There must be some kind of problem when trying to locate the FLV file in Dailymotion.
With the other website I tried, no problem.
Nevertheless, it's better than the first version of Flash Video Downloader. Fix the problems with Dialymotion and it'll be a great app.
(Yes... I know I can download FLV file from Safari's activity window and from Firefox with the DownloadHelper extension.)

Unfortunatly, videodownloader.net still doesn't work for all videos, which makes Flash Video Downloader not work for all videos. I'm very close to finishing a brand new completly re-written version of Flash Video Downloader that won't have this problem.
